Gluten-Free Lemon Cake (With a Secret Ingredient!)

We can’t wait to try this lemon cake recipe from Hugh Fearnley-Whittingstall of River Cottage. In addition to ground almonds, it contains one very unexpected – and gluten-free – ingredient…

…mashed potatoes!

Fearnley-Whittingstall says, “The idea for this lovely, moist cake came from Elena Wong on our production team. It’s best made with leftover whole potatoes, which you’ve mashed or, even better, riced once cold.” (Just make sure that if you’re using leftovers, they don’t contain too much butter, milk, or other seasonings!)
